Nvidia CEO Jensen Huang also offered a counterintuitive prediction about how robots will affect human jobs.

My dog is smart, but without an opposable thumb, he still can't open the door to let himself out. Humanoid robots have a similar problem. Why it matters: Despite huge breakthroughs in artificial intelligence that enable these clever machines to learn from human feedback or their environment,

Agibot just released a robot dog, a factory-worker humanoid robot on wheels, a "white-collar" humanoid robot for reception-like duties, and a playful dancing robot.

Hyundai-owned Boston Dynamics is also partnering with former owner Google's DeepMind on AI, in a full-circle moment for the two companies.

Chinese company Agibot showed up with two: the human-sized A2 and the slightly smaller X2, both of which were displaying their surprisingly impressive dancing abilities.

Robot dogs dancing to K-pop and the first public appearance of Boston Dynamic's product version of its Atlas humanoid robot are the highlights of Hyundai's CES tech showcase.

Waymo, the largest purveyor of self-driven transport, says on its website that its robotaxis are “ the embodiment of fully autonomous technology that is always in control from pickup to destination.” Passengers “can sit in the back seat, relax, and enjoy the ride with the Waymo Driver getting them to their destination safely.”

Hyundai admits humanoid robots in car factories will change the nature of work—but don't expect much of an impact on prices.
